Spider Mounting Bracket Installation..................................................... 100 SecureLinx Spider User Guide 7 1: Preface Purpose and Audience This guide describes how to install, configure, use, and update the SecureLinx Spider device. It is for users to remotely and securely provide monitoring and control of one target computer system by one or more remote users. Additional Documentation The following guide is available on the product CD or the Lantronix Web site: www.lantronix.com. Document Description Spider View User Guide Details instructions on using the Spider View utility. SecureLinx Spider Quick Start Guide Provides an overview of using the Spider. SecureLinx Spider User Guide 8 2: Introduction This chapter introduces the Lantronix SecureLinx Spider (SLS) line of KVM-over-IP devices. It provides an overview of the products, lists their key features, and describes the applications for which they are suited. The SecureLinx Spider is a distributed KVM-over-IP device designed to remotely and securely provide monitoring and control of one (target) computer system by one or more remote users. The remote user (client) accesses the Spider over a local or wide area network connection using a standard web browser. The Spider provides secure, remote IP-based access to Keyboard, Video, and Mouse (KVM) on the attached server, and makes it available to anyone who can access the Spider’s IP address. Spider is an evolution of the traditional remote KVM switch into a compact package. It is light enough to be cable-supported from the back of a server and takes up no rack space. There are four models: one with both PS/2 and USB keyboard/mouse interfaces (software selectable), one for USB-only systems, and two variations of cable length (21” and 58”) for each. The Spider is unique in that it is low-enough in power consumption to be powered from the attached server. The color-coded plugs on the ends of the cables for the keyboard, mouse, USB port and video are designed to plug directly into the target system’s corresponding connectors. An optional external AC/DC power supply is available. The Spider differs from other KVM-over-IP switches in several ways. Unlike rack mount KVM-over-IP switches, the allocation of one Spider per computer allows add-as-you grow scalability and guarantees non-blocked BIOS-level access to mission-critical servers regardless of the number of remote users or servers that need access. Also, Spider is unique in that it uses Lantronix SwitchPort+ technology to incorporate two hardwareswitched Ethernet ports, one for the primary network connection and the second for daisy-chaining Spiders, or aggregating other Ethernet connections (for example, a dedicated management LAN port on the controlled system). This provides a costeffective solution in environments where numerous cable drops and distance limitations can be a challenge when adding servers. Note: The terms Remote Console and KVM Console are synonymous and used interchangeably throughout the User Guide and Spider. Features Secure, full BIOS-level control of remote servers over an IP network Space saving “zero footprint” package attaches directly to the server – saves rack space Flexible 1 port design allows you to scale as you grow Server-powered design - no external power supply required Guaranteed non-blocked access to remote servers – ensures lowest “cost-perremote user” SecureLinx Spider User Guide 9 2: Introduction Browser based - no client software or special licensing required No video degradation with long Cat-5/6 cable runs (up to 300 feet) - eliminates cable distance limitations of typical rack-mounted analog/CAT5 KVM switches Lantronix SwitchPort+ technology allows Spiders to be cascaded or share a host’s Ethernet connection Virtual Media support allows local drives (floppy, CD, hard drive, USB stick) to be shared with the remote server or to remotely install an O/S from an .ISO image Direct KVM minimizes the number of clicks to the remote server’s console Built-in RS-232 serial port can be configured for serial console pass-through or remote dial-in access Ideal for Distributed IT systems environments such as small branch offices, campuses, test labs, and server hosting environments Functionality The Spider contains an embedded web server, dedicated hardware, and control firmware that: Captures the video output from the attached computer. Compresses the video and serves it up over the network to a Java KVM console window launched by the browser or to a command line on the user’s system, which draws a replica of the server’s video output on the user’s monitor. The Java KVM console then − − − − Accepts keystrokes and mouse movements on the user’s system. Recognizes those intended for the target computer. Transmits those to the Spider. Emulates a physically attached keyboard and mouse to spoof the computer into thinking the user is sitting next to it Figure 2-1.

Package Contents In addition to the Spider distributed KVM/IP module, the box contains the following items: Null modem DB9F to RJ45 serial cable Mounting kit (For details, see D: Mounting Bracket Kit for the Spider (083-015-R) Quick Start Guide CD-ROM containing documentation and utilities Note: An optional external AC/DC power supply is available. Configuration Planning Consider the following factors when determining how to use the Spider in an environment: Keyboard/Mouse Interface The USB interface is typically preferred as it provides better remote cursor tracking. Some older systems do not have BIOS supporting USB human interface devices or there may not be two available USB ports. In these cases, the PS/2-interface model may be required; note that for this model the USB or PS/2 interface keyboard/mouse may be selected via software. Spider Serial Port The RS-232 port on the Spider is used for initial configuration of setup parameters, but it can subsequently be used to connect to a target’s COM port. The Spider allows remote users to Telnet or SSH to that port, eliminating the need for a separate box to perform serial command line management. Alternatively, the serial port can be used for PPP connection to the Spider’s user interface so that remote users can access the Spider via a modem or other serial interface. This could be either the primary network connection or a backup in case the primary LAN connection is unavailable. Redundant Power The Spider draws all of its power from the attached server, eliminating the need for external power supplies. Note that if the server loses power, the Spider loses power as well. With an optional auxiliary DC supply fed from an independent AC power source, the Spider will always have power regardless of the state of the server. SecureLinx Spider User Guide 13 3: Installation Second Ethernet Port The Spider incorporates a hardware Ethernet switch connecting the external two ports and the internal CPU for many possible configurations. The first port is required for connection to the network. Potential uses for the second Ethernet port: Tying all the Spiders in a rack together so that only one external network connection is required. While this configuration physically is a chain, logically each Spider is addressed directly from the outside network. Because the data from the Spider at the end of the chain does need to traverse the entire series of switches, latency increases and hence responsiveness degrades with the number of devices. A maximum of 16 Spiders in a chain is recommended, though this is a function of the type of application and acceptable level of response. If the switch to which the Spider chain is networked supports Spanning Tree, the first and last devices in the chain may both be connected to the same switch to provide resilience against a single point failure. Connecting to the attached server’s LAN management port; an external management network can then interface to both the Spider and the server via one cable. Connecting to the attached computer’s main LAN port. If physical isolation of management data and user data is not a concern, a single LAN cable can provide connectivity to both Spider and computer, conserving a switch or router port. Aggregating any other Ethernet connection as a general-purpose switch port. Batch vs. Individual Setup It may be necessary to deploy a batch of Spider devices at once. In that case, stage them on a bench for pre-configuration before attaching them to their respective computers. Some tips for configuring a batch of Spiders: The keyboard/video/mouse connections are not required for setup. All you need are a source of power and a serial connection to set up the network parameters, and an Ethernet connection to access the administration user interface. The quickest and easiest source of power is the auxiliary DC input. DC supplies are available from Lantronix under order number 520-085-R. If using a third party charger with mini-USB connector, make sure it is 5V@1A regulated (“Efficiency level III” or “IV” is an indicator that it is a switching supply and hence well regulated) with an adequate cable. Tag each Spider with its IP address or write it on the serial number label on the bottom.

Plug the RJ45 end of the included serial cable into the Spider’s serial port. Plug the DB9F end into the serial (COM) port of a PC/laptop running a terminal emulator (e.g., HyperTerminal). The default serial port settings are 9600 bits per second, 8 data bits, no parity, 1 stop bit, no flow control. 2. The Spider is typically powered by the attached server. Plug the Spider video, USB, and PS/2 keyboard/mouse (if applicable) cables into the target computer (this is required for the device to boot up). The two blue power LEDs will illuminate and the green system OK LED flashes to indicate that it is booting up. Bootup is complete within approximately one minute. The system OK LED stops flashing and remains illuminated. SecureLinx Spider User Guide 15 3: Installation 3. Upon bootup, the terminal window displays the login prompt. To change the default IP auto configuration from DHCP to a static IP address, type config and press Enter. 4. At the IP autoconfiguration prompt, type none and press Enter. 5. Follow the prompts to enter the unit’s IP address, subnet mask, default gateway, and LAN interface information. 6. Type Y, followed by Enter, to accept the changes. The system takes several seconds to update the internal protocol stack and display the updated information. 7. Plug an Ethernet cable connected to your network into the Ethernet port. The Link LED illuminates. Assigning a Static Address with Detector Use Detector to replace an automatically assigned IP address with a static IP address. Note: Detector can be downloaded from the Lantronix website http://www.lantronix.com/support/downloads.html. Note: If you try to run detector2.exe on a network shared drive, you may get a security exception. We recommend that you run the program on the CD or copy the detector2 directory to your local hard drive and run it from there. If you must run detector2.exe from a network shared drive, you need to change your security settings using the" .NET Framework Configuration" or "caspol" tool. To install .NET required by the Detector: 1. Double-click detector2.exe on the product CD. 2. If a "The application failed to initialize properly (0xc0000135), click OK to terminate the application" message displays, you need to install .NET Framework. 3. Obtain the .NET Framework redistributable package from the Spider CD. It is also available as a stand-alone executable file, Dotnetfx.exe. You can download this from Microsoft at: http://www.microsoft.com/downloads/details.aspx?FamilyID=0856EACB-43624B0D-8EDD-AAB15C5E04F5&displaylang=en SecureLinx Spider User Guide 16 3: Installation To use Detector to set the IP address: 1.

You can now access the unit using the new IP address. Target Computer Setup Video The Spider recognizes a wide variety of VESA, Sun, and Apple video resolutions up to a maximum of 1280x1024@60 Hz; the complete list of supported video formats is in C: Supported Video Formats SecureLinx Spider User Guide 18 3: Installation To minimize power consumed in the server and attached Spider, set the monitored server’s video resolution to the minimum necessary for your remote monitoring application. We recommend 1024x768 or 800x600 if connecting the Spider over a wide area network rather than a LAN. 1280x1024 may be used for applications demanding higher resolution; however it consumes more network bandwidth. The other supported formats are recognized by the Spider, but may offer difficulty if the timing does not comply with the applicable standard. The Spider supports the extended display identification data (EDID) standard for informing the attached computer of its supported video formats. On a Windows target system, select Control Panel Display Settings. Modify the screen resolution value as necessary. Select Control Panel Display Settings Advanced Monitor. Modify the screen refresh rate (consult the appropriate documentation when using an atypical video card or another operating system on the target computer). Since the server's video output is driving the Spider and not a monitor, a refresh rate higher than 60 Hz has no effect. For Linux systems, edit the Xfree86 file XF86Config to disable formats that are not supported or not VESA standard timing; a reboot is required. If you are using a special video card or another operating system on the target, consult the appropriate documentation. Solaris servers may need to be set to output H+V sync, not composite sync. The powerdown-monitor settings in the operating system’s power management have no effect on the Spider’s internal operation and network interface, but if the attached server is in a monitor power-down mode the client application displays “No Video” and the Video LED will be out. The “Video” LED on the Spider actually monitors the vertical sync signal, not the video data itself. Background wallpaper and desktop appearances do not have any particular limitations, although Microsoft Active Desktop and Linux graphical interfaces’ virtual desktop are not supported. If bandwidth is a concern, plain backgrounds are preferred. Mouse Mouse to cursor synchronization has long been a troublesome issue with digital KVM interfaces. PS/2 mice transmit incremental information about movement over a period of time, not an absolute measurement; the driver in the operating system then translates to distance based on the local screen resolution and applies linear or nonlinear acceleration mappings. When a remote client system is communicating with the target system, settings and screen resolutions on both sides of the connection must be taken into account in order to get natural mouse-to-cursor tracking. Use the USB keyboard/mouse when supported by the target computer. Unlike the PS/2 interface, a USB mouse uses absolute coordinates rather than relative coordinates and hence does not present the difficulties in translation between local and remote systems. On the PS/2 model Spider, when the keyboard/mouse interface is set to Auto it will first attempt to use the USB interface and only if it does not detect support in the attached OS will it fall back to PS/2. There are no restrictions on the mouse settings of the client systems. And as a rule, no special care must be taken on setting mouse parameters of target systems when using the USB mouse interface. For the PS/2 interface, performance (tracking) and synchronization can be optimized by removing any special acceleration or nonlinear ballistics. For several common operating systems: SecureLinx Spider User Guide 19 3: Installation On a Windows target system, select Control Panel Mouse Pointer Options. Set the pointer speed to medium and disable Enhanced pointer precision. Linux graphical interfaces. Set Mouse Acceleration to exactly 1 and threshold to exactly 1. Also, select Other Operating Systems on the Spider mouse settings page. Sun Solaris. Adjust mouse settings via the CDE control panel to “1:1, no acceleration” or via “xset m 1”. Mac OS X. Set Spider to Single Mouse Mode. Serial If you plan on using the Spider to Telnet or SSH to the target system’s serial port, set that port to match the Spider’s equivalent settings. The Spider’s default serial settings are 9600 bps, 8 data bits, 1 stop bit, no parity, and no flow control. The pinout of the included cable matches a standard DB9 COM port. Cabling Connections for video, USB, and keyboard/mouse are integrated into the Spider. Do not use extension cables; plug the Spider directly into the appropriate ports on the host system. If using the serial port, cable it to the appropriate COM port on the server. The second Ethernet port (cascade) may be used to connect to the target computer’s management LAN port or main LAN port, or to chain Spiders. When connecting the Ethernet ports, either straight through or crossover cables may be used, as the Spider has both auto-polarity and auto-crossover correction. Although both the port marked Ethernet and the port marked Cascade are Ethernet interfaces, you must use the port marked Ethernet if using only one Ethernet interface. When chaining Spiders, bring the outside network cable in to the left Ethernet port of the first Spider. Connect the right Cascade port to the left port of the next Spider in the chain. Repeat as necessary. The last Spider in the chain will have its right port unoccupied, unless cabling in a loop for redundant connection. The downside to chaining Spiders is that a break in the cabling or device failure results in a loss of network connectivity for all Spiders downstream of the fault. This can be averted if the switch or router to which the Spider chain attaches supports Spanning Tree, and has it activated. In that case, the last Spider can have its Cascade port tied back to the same switch so that there is a redundant outside connection. The Spanning Tree protocol implemented in the switch will disable one of the two network connections while the loop remains complete; data will flow in only one direction around the loop. If the loop is broken, it activates both connections, so that data can flow in both directions. All Spiders will be accessible except the one immediately downstream from the break or down unit. Do not try this without Spanning Tree in place. Client Setup Two mechanisms are provided for monitoring Spider-connected targets at client systems. Spider View is a standalone Windows application that can locate, manage, and access multiple Spiders from an integrated view. Spider View requires a client to be running Windows XP or later and have ActiveX controls enabled. Please refer to the separate Spider View User Guide for instructions on installation and operation of Spider View. SecureLinx Spider User Guide 20 3: Installation For platform-independent management, each Spider contains an embedded web server that delivers web pages, a Java KVM remote console program, and a terminal program. The client system must have a web browser (Spider supports browsers such as Internet Explorer 6.0+, Netscape 5.0+, FireFox 1.0+, and Safari 2.0+) in order to access and administer the Spider. To run the actual Remote Console window and manage the target system, a Java plug-in is also required. To run the actual Remote Console window and manage the target system, a Java plug-in (Sun JRE 1.4 or later) is also required. Network Environment The connection between client and Spider must be open to IP traffic and have TCP ports 80 (HTTP) and 443 (HTTPS) open. Firewalls and NAT devices may need to be configured to support this; consult your system administrator. The TCP ports used by the Spider may be changed at Interfaces Network. When idle, the Spider generates minimal network traffic but when images are rapidly changing on the host system and image quality is set to the maximum there can be bursts of traffic exceeding 10 mbps; fast Ethernet connections are recommended. In a local area network, the responsiveness of the Remote Console window will be affected by traffic; a switched network environment is advised. Power The Spider is low enough in power consumption (under 4 watts) to draw its power from the attached computer. However, it requires all cables to be plugged in to receive sufficient power. Plug in both USB cables or a USB and a PS/2 cable. The Pwr1 LED indicates that power is available on the first USB port. The Pwr2 LED indicates that power is available the second USB port, or the PS/2 ports. The Spider will not start up until both Pwr1 and Pwr2 LEDs are on. It then begins to blink the SysOK LED, which will continue to blink while the boot process continues. The Spider is Linux-based, and takes about a minute to boot. When the SysOK LED is on steady, the Spider is up and ready to communicate. The Spider can also derive power from an external DC supply. DC supplies are available from Lantronix under order number 520-085-R. The DC supply is most useful as a backup, as the Spider will otherwise lose power if the attached computer does. In addition to power-on reset, the Spider can also be rebooted from the user interface, from the serial port, or by clicking the reset switch through the pinhole on the back of the body. SecureLinx Spider User Guide 21 4: Web Browser Access The SecureLinx Spider controls a target computer by redirecting its human interface peripherals of keyboard, mouse, and video screen to one or more other (client) computers. The Spider achieves this by serving up web pages and launching a Java KVM console across the network connection to the client using standard protocols (such as IP, TCP, and HTTP/HTTPS). The Java KVM console window running on the client system appears as a preview of the target computer’s screen. Note: The Spider supports browsers such as Internet Explorer 6.0+, Netscape 5.0+, FireFox 1.0+, and Safari 2.0+. When using the Spider View application on Windows, refer to the Spider View User Guide. This section refers to the Spider connection via a web browser. 1. Access the Spider over the network using a web browser by entering: https:// (for a secure SSL connection) or http:// (for an insecure connection) and its IP address in the address bar. The browser must accept cookies for login. 2. Enter your user name (default is sysadmin) and password (default is PASS) at the prompt. The Spider home page displays. Figure 4-1. Spider Home Page After passing authentication, the Spider opens the home page, from which the Remote Console or Telnet Console may be launched. The home page contains a snapshot of the target system’s video in the Remote Console Preview window, various pieces of SecureLinx Spider User Guide 22 4: Web Browser Access information (session and host name), a series of tabs along the top left, and buttons, including a Logout button, along the top right. At this point, you are logged in with all permissions to make changes to configuration and user database. You may then set the unit up for either local or remote authentication for other users, and define their permission level. As sysadmin, you may also make changes to the hardware settings, establish configuration parameters, and perform maintenance operations. SecureLinx Spider User Guide 23 5: Remote System Control The Spider’s primary function is running the Remote Console (Remote Console). The Remote Console window has settings that apply each time a user launches it. Other settings may be applied within the window itself. By scaling the window down in size, it is possible to have multiple Remote Console windows open, allowing interaction with multiple target systems. KVM Console To launch the Remote Console window: 1. Click the KVM Console button to launch the Lantronix Spider Remote Console. The Remote Console window may open in the foreground or in the background. If it launches in the background, click on the icon to bring the window to the front. Alternatively, launch the Remote Console by clicking the link below the preview image on the KVM Console Preview window. Note: You can enable the Spider to bypass the web page and take you directly to the remote system. This capability is called Direct KVM. The Remote Console window shows a real-time replica of the video output from the target system (mimicking a monitor plugged directly into the remote computer). When the local computer’s focus is within the Remote Console window, mouse movements and keystrokes are transmitted to the remote computer. The title bar of the window shows the IP address of the Spider providing this view (useful when multiple windows are open on the client system). The Remote Console window is like any other window on the client system. It may be minimized, maximized, or scaled in either direction. SecureLinx Spider User Guide 24 5: Remote System Control Console Window Components Title bar and IP address Toolbar Button keys Main viewport Information Bar Main Viewport and Scroll Bars When first launched, the full virtual screen of the target computer is mapped pixel-forpixel to the console window’s main viewport. As a result, if the target is running at a resolution less than that of the client, the entire screen is visible in the Remote Console window. If the resolution is such that the screen does not fit, scroll bars are available in the Remote Console window to move the viewport around within the target’s screen. The virtual screen size of the target may also be scaled down to match the Remote Console window. Button Keys Along the top there are Button Keys that have been defined to send special key codes directly to the target computer. Toolbar The top toolbar has a number of buttons for one-click access to functions, and a dropdown menu where other options may be reached. The icons vary depending on which keyboard interface is active. Access Virtual Media The leftmost diskette icon is used to activate the Virtual Media toolbar. SecureLinx Spider User Guide 25 5: Remote System Control Auto Adjust Video This button activates the Auto Adjust Video function. When first opening the Remote Console window, it is recommended to click this button to ensure the Spider has locked on to the video format on the attached computer. Also, click this button if there is an offset from the proper horizontal or vertical start position relative to the target screen (black bars to the right, left, top, or bottom of the main viewport, or a distorted video). Screen Display Adjustments These 3 buttons (A,S,R) facilitate changes to the Screen display Sync Mouse, Single/Double Cursor These icons appear when the PS/2 mouse interface is active. Options The drop-down menu provides access to a number of options and features. Information Bar - Connection The left side of the information bar indicates whether the connection is encrypted (Console (SSL)) or unencrypted (Console (Norm)). Information Bar - Resolution Displays the horizontal by vertical resolution of the target system’s video. Information Bar - Network Traffic Displays the approximate number of bytes per second incoming and outgoing to the window. An indication of the number of frames per second (fps) updated is also displayed. Incoming data is generally comprised of video updates. Outgoing data is generally comprised of keystrokes and mouse movements. When the target screen is not changing, In should be low or zero. If not, click the auto-adjust button. The amount of network traffic is a function of the detail in the captured screen, the rate at which the screen is changing, and the video encoding settings. Concurrent Access State One user is connected to the Remote Console Multiple users are connected to the Remote Console This user has exclusive access to the Remote Console. No other clients may access the target system until exclusive access is disabled. Another user has exclusive access to the Remote Console. No other clients may access the target system until exclusive access is disabled by that user, or until that user closes their Remote Console window. Monitor Only State The far right icon shows whether this client may interact or simply view the target computer. Monitor Only is disabled; keyboard and mouse may interact with the target. Monitor Only is enabled; this client is view-only. SecureLinx Spider User Guide 26 5: Remote System Control Exclusive Access Only one user may access the Spider at a time. Basic Remote Console Operation The “focus” of the client computer is the location of where the cursor is pointed. When the Remote Console window is open, there are three zones where the focus may be pointed: 1. Outside the Remote Console window, interaction is with the local computer’s operating system or applications. 2. Inside the Remote Console window’s viewport, interaction is with the target computer. 3. Inside the Remote Console window but outside the viewport, interaction is with the Remote Console control functions such as the toolbar or scroll bars. Figure 5-1. Remote Console Window Within the Remote Console viewport, interaction with the remote computer is generally the same as if there were a direct connection (with a minor lag due to network latency). Windows may be opened, applications run, settings changed, maintenance functions performed, even system reboots performed. Powering down the target computer results in powering down the Spider as well (unless the redundant supply is used). SecureLinx Spider User Guide 27 5: Remote System Control Figure 5-2. Remote Console Toolbar Mouse/Cursor Synchronization and Operation Typically, mouse to cursor synchronization is an issue with digital KVM interfaces. Use of the USB mouse interface solves the problem, however many systems rely on a PS/2 interface. Spider provides several methods to fix the de-synchronization of local and remote cursors. Auto Video Adjustment The left side of the target computer’s screen must be aligned with the left side of the Remote Console viewport so that the tops align as well. If not, the local and remote cursors will always have a fixed offset of that amount, even if the USB interface is used. Clicking the Auto Video Adjustment one or more times typically cures any offset. Screen Display Adjustments Three features are added to the toolbar to facilitate Screen display changes: A – Full Screen Mode (Ctl+F10). S – Full Screen Stretch Mode (Ctl+F10 to return to regular mode). R – Full Screen Mode with Changing Client Monitor Resolution (Ctl+F10 to return to regular mode). Fast Sync and Intelligent Sync The Spider uses two different algorithms for re-synchronizing local and remote cursors. Use the Fast Sync button on the toolbar to correct a fixed skew. Intelligent Sync uses a different algorithm and is useful when the mouse settings have changed on the remote system or when Fast Sync does not work. It is accessed through the Options Mouse Handling drop-down menu. The Sync button on the toolbar usually performs a Fast Sync, but will perform an Intelligent Sync if the video format has recently changed. Single and Double Mouse Modes Continuous synchronization of local and remote cursors may not be feasible. The Spider provides a mode where only one cursor is visible when operating in the active Remote Console viewport. Click the Single/Double button on the toolbar to activate Single Mouse Mode. This is indicated by a single arrow in the Single/Double button. When in this mode, the Java KVM console “grabs” the local cursor after clicking within the viewport and will not release it until a “release-cursor” hot key sequence is given (Alt+F12 by default). As there is only one cursor, and that one is confined to the active viewport, there is no issue with local to remote cursor tracking. There also is no local cursor; Alt+F12 is required to free the cursor to move the focus from the active viewport. Clicking when the local cursor is within the viewport will re-grab the cursor. Single Mouse Mode may be exited by clicking on the Single/Double button. If at some point the cursor seems to disappear, click Alt+F12 or check the Single/Double Button as Single Mouse Mode may have been entered in error. Note: Single Mouse Mode requires Sun Java 1.4 or higher SecureLinx Spider User Guide 28 5: Remote System Control Local Cursor The Spider has an option to change the appearance of the local cursor when the focus is on the remote computer. Select Options Local Cursor and select one of the following cursor options: Default: the local cursor maintains its appearance regardless of the focus location Transparent: the local cursor is invisible when the focus is on the remote computer. This is similar to Single Mouse Mode except the cursor is not “grabbed” and will reappear when moved outside of the active viewport. The other selections provide a change of appearance for a visual clue that the focus is on the remote computer; the cursor changes back when the focus is back at the client system (including those areas of the Remote Console window outside the main viewport.) Selections made in the Local Cursor submenu are associated with the current user and will be saved for the next Remote Console session. Optimizing Video Auto and Manual Video Adjustment The Spider automatically recognizes and adapts to many standard video formats. (The complete list is in Appendix C.) When it first enters the Remote Console window, it recognizes and locks onto the video in order to provide a picture as soon as possible. Once within the window, click the Auto Video Adjustment button once or twice to provide a greater degree of optimization. The Auto Adjustment process analyzes the timing of the incoming video’s horizontal and vertical sync signals then adjusts the digitizing hardware parameters. If there is slightly nonstandard timing, these parameters may be manually fine-tuned. If it is necessary to adjust video hardware parameters, this may be done from Options Video Settings. This brings up a window with a number of slider bars. Adjust the brightness and contrast of the Remote Client window as presented by the Auto Adjustment. This is a hardware parameter and applies to all Spider users. Overall brightness and the contrast levels of each of the red, green, and blue primaries may be modified up or down. The Remote Console window immediately reflects the change. Once there is a satisfactory color-mapping, click Save Changes to retain those colors permanently for that video format. To discard the changes made, click Undo Changes. To return a particular setting or all settings to the original factory defaults, click Reset this Mode or Reset All Modes. Clock and Phase The A/D converter uses these low-level settings in the digitization process. Adjustment should not be required unless advised by Lantronix Tech Support. If the timing of the video signal is slightly off, the Auto Adjustment may not capture the frame at the right point. This will result in black bars along left, right, top, or bottom of the Remote Console viewport, and cutting off the opposite side of the captured image. The Offset sliders can be used to align the sides properly. Once there is correct alignment, click Save Changes to retain those settings permanently. To discard the changes made, click Undo Changes. To return a particular setting or all settings to the original factory defaults, click Reset this Mode or Reset All. SecureLinx Spider User Guide 29 5: Remote System Control Video Encoding Various video encoding schemes have been defined to try to tailor the bandwidth usage to what is available. In addition to the predefined schemes, compression levels, and color depth can be manually adjusted. The default settings for each user are established in the KVM Settings User Console Transmission Encoding web page. To change the settings during a session, select Options Encoding Predefined, Encoding Compression, Encoding Color Depth, and Encoding Lossy manual adjustments. These settings will be lost when the Remote Console window is closed; for nonvolatile changes use the KVM Settings User Console Transmission Encoding web page. Scaling Target Video to Client Resolution In addition to the 1:1 pixel mapping mode, which is the default when the Remote Console window is first launched, scaling factors may be applied to the captured video in order to match various sizes of windows on the client. This scaling may be a fixed ratio or dynamically adjustable, as selected from the Options Scaling selection. 100% is the default; it may result in a viewport smaller than the virtual screen and is moved around with scroll bars. 25% and 50% selections are optimal for viewing several target systems concurrently. Keyboard Functions The Spider provides a number of useful functions for mapping or translating between the local keyboard/keycodes and the emulated keyboard presented to the target computer. Soft Keyboard With remote control of a computer, it may be that the target system and client system are in different countries, using different languages. By using a Soft Keyboard, the local user can have the keycodes available to send to the target that are not on the local keyboard, without worrying about OS and application character set mappings. Select Options Soft Keyboard Mapping to get a submenu listing the languages supported. Make the desired selection, and then verify it with Show soft keyboard. Select Options Soft Keyboard Show. This provides an image of the currently selected Soft Keyboard. The Soft Keyboard sends single keystrokes as well as combinations of keys such as Ctrl+C. For a single keystroke, click on the button with the desired character. Single keys such as alphanumeric characters and punctuation are sent immediately. Special keys such as Ctrl, Shift, and F1 to F12 must be selected twice. The first click sends the signal “key is clicked.” The second click indicates the signal “key is released” to the remote system. After the first click the button will change its color to indicate that the key remains clicked, and that a code has not been sent. After the second click the button will appear as usual, showing that the keycode was sent. Click the Close button on the title bar to close the soft keyboard. Local Keyboard The Java Virtual Machine running the Remote Console applet on the client computer determines its keyboard language mapping automatically from the operating environment. There may be circumstances where it is unable to do so, such as when the keyboard mapping and OS language do not match. The Options Local Keyboard SecureLinx Spider User Guide 30 5: Remote System Control selection allows manual designation of the language/layout of the keyboard on the client system. Hotkeys Hotkeys provide an alternative method for sending keycode sequences defined in the section on Remote Console Button Keys. Click Options Hotkeys and select the Button Key to be sent. If that Button Key has been defined with “Confirm”, a confirmation dialog box pops up before the keycode is sent. Other Remote Console Functions Monitor Only When Options Monitor Only is checked, the keyboard and mouse are disabled for this Remote Console window. The Monitor Only state is shown in the lower right corner of the Remote Console status bar. The user must have the appropriate permissions to change this setting. Exclusive Access When Options Exclusive Access is checked, no other client may open a Remote Console window to this Spider. Any open Remote Console windows on other clients will be disconnected. The Exclusive Access state is shown in the lower right corner of the Remote Console status bar. The user must have the appropriate permissions to change this setting. Screenshot to Clipboard Options Screenshot captures a snapshot of the entire target system’s virtual screen to the clipboard for pasting into other applications. Refresh Video The entire Remote Console viewport area is redrawn when the Remote Console window is first opened, and when the Auto Adjust Video button is clicked. As the encoding settings and noise filter may sometimes result in visible compression artifacts, selecting Options Refresh Video can be used to redraw the entire viewport area. Telnet/SSH In addition to interacting with the target system using the KVM Console, the Spider also allows text communication with the target via the Telnet Console, also a Java program window. Telnet and SSH are network protocols that enable a tunnel from the client system to the Spider’s serial port. Once set up, it may be accessed through the web interface at the Telnet Console window, or using a Telnet/SSH client to connect directly. Note that Telnet/SSH cannot be used to connect to the Spider itself in order to control it, as the Spider has an HTTP and not a command line interface. The Telnet Console is a Java program and has the same Java Runtime Environment requirements as the Remote Console. When the Telnet Console window is open, the user at the client system can send and receive characters directly to the serial port. SecureLinx Spider User Guide 31 5: Remote System Control Set up and Enable To use Telnet or SSH, the serial port must be put in passthrough mode with the appropriate connection parameters and cabling with Telnet and/or SSH access allowed. If desired, the TCP port numbers also may be changed from their defaults. A user attempting to connect via Telnet or SSH must also have the appropriate permissions. Passthrough Use When using Telnet/SSH in passthrough mode, the Spider just acts as a conduit for the serial data traveling between the client system and whatever is connected to the serial port. This may be a COM port on the remote computer, or a serially controlled power strip, or anything else with an RS-232 port. 1. From the client system, use a Telnet or SSH utility to connect to the IP address of the Spider, at the assigned Telnet TCP port number. 2. The Spider will present LOGIN and PASSWORD prompts. Enter a valid user name and password. The user must have permissions set to use Telnet or SSH. 3. The Spider will reply with a Welcome and status, followed by a command line prompt. Selections are: Help – displays a list of commands Version – displays the current Spider firmware version number Connect Serial – enter passthrough to serial port mode Logout – terminates the Telnet or SSH connection 4. Enter connect serial to open the connection to the serial port. 5. You are now connected and may interact with the attached serial console. Keystrokes are not locally echoed and must be echoed by the connected serial device. 6. Use the SSH or Telnet ability to send and receive serial data between the client and the serial port. The Spider does not echo this data back to the client. 7. When complete, enter Esc-Exit to return to the command line. 8. Enter logout or l to close the connection. Telnet Console Use When using the Telnet Console, the Spider opens a window on the client system that provides direct access to the Telnet/SSH command line. This eliminates the need to have a Telnet or SSH utility running on the client system. 1. Click the Terminal button at the top of the Spider page. The user must have permissions set to use Telnet or SSH. The JRE will launch, and the Telnet Console window appears. Telnet Console and Remote KVM Console windows may be open concurrently.

SSH port Port number at which the Spider’s SSH server is listening. The default is 22. Bandwidth Limit The maximum network traffic generated through the Spider’s primary Ethernet port, in kilobits. If left blank, there is no bandwidth limitation applied. Enable TELNET/SSH access For security, the default is having Telnet and SSH disabled. Check the appropriate box (es) and set up the serial port for Telnet/SSH to use the Telnet console. Disable Setup Protocol Spider View uses a special protocol to locate and set up Spider IP addresses. As a security measure you may wish to disable this protocol when deploying Spiders. If the protocol is disabled, SecureLinx Spider User Guide 35 6: Interfaces Detector and the Spider network will not find the Spider. Enable remote console proxy access Enable the Java KVM console program to use a proxy server to connect to the Spider. If you must configure your web browser to use a proxy server, you will likely have to do the same on the Spider. Proxy host Enter the proxy server's address. Proxy port Enter the proxy port number. 3. Do one of the following: Click Save to save settings. Click Reset to Defaults to restore system defaults. Click Reset to restore original settings. Serial Port Settings After using the serial port to set up the Spider’s network parameters, you may put the serial port to another use. You may establish A PPP connection to use a modem or other serial connection to log in to and operate the Spider. If you want to access a console port remotely through the Spider, SSH and Telnet passthrough is available. To configure the serial port: 1. Click Interfaces Serial Port. The Serial Port Settings page displays. Figure 6-2. Serial Port Settings Page 2. Modify the following fields: Configuration Login Select this option to use the serial port locally only to set up network parameters or reset the unit. Modem Connect to the Spider with a dial-up or ISDN connection, using PPP. Essentially, the Spider acts as an ISP that you dial in to. The SecureLinx Spider User Guide 36 6: Interfaces client system will need to be set up accordingly, for example using the Windows Network Connection Wizard. Change the following parameters as necessary: Serial Line Speed: Most modems support 115200 bps. Modem Init String: The initialization string sent out to set up the modem. If you have a special modem or are going through a PBX requiring an access sequence, you may modify the string. Consult the modem’s manual on the AT command syntax. Modem server IP addresses: As part of the PPP handshake, IP addresses are assigned to the remote device. Modem client IP address: IP address assigned to the Spider. Passthrough Access to serial port 1 via Telnet/SSH The serial port may be used to connect to the target server’s COM port for integrated access to command line functions or used to control a serial-interfaced peripheral. Telnet and SSH are network protocols that enable a tunnel from the client system over the network to the Spider’s serial port. Once the port is set up, it may be accessed through the web interface at the Telnet Console window, or using a Telnet/SSH client to connect directly. Set the following parameters to match connected equipment: Speed: The speed with which the device port exchanges data with the attached serial device. From the drop-down list, select the baud rate. Most devices use 9600 for the administration port, so the device port defaults to this value. Check the equipment settings and documentation for the proper baud rate. Data bits: Number of data bits used to transmit a character. From the drop-down list, select the number of data bits. The default is 8 data bits. Parity: Parity checking is a rudimentary method of detecting simple, single-bit errors. From the drop-down list, select the parity. The default is none. Stop Bits: The number of stop bit(s) used to indicate that a byte of data has been transmitted. From the drop-down list, select the number of stop bits. The default is 1. Flow Control: A method of preventing buffer overflow and loss of data. The available methods include none, software (xon/xoff), and hardware (RTS/CTS). The default is none. 3. Do one of the following: Click Save to save settings. Click Reset to Defaults to restore system defaults. Click Reset to restore original settings. SecureLinx Spider User Guide 37 6: Interfaces KVM Console Settings User Console The Remote Console window into the target system has settings that may be changed for the way each individual user interacts with the Spider. When a user is created by copying from an existing user, the Remote Console settings will be copied as well. You can change these settings on the Interfaces KVM Console Settings page. Note that if you are using the Spider View application, these settings do not apply; see the Spider View User Guide for further information. The way in which the Spider transmits video data back to the client system can be tailored for the type of network connection. On a LAN where bandwidth is not an issue, compression is not required and the speed of updates can be maximized. For other connections, the optimum user interaction needs to trade off image quality and update speed to fit the size of the pipe. Because various users may be accessing the Spider over different connections, these parameters are applied on a user-by-user basis. The default is set for maximum image quality and speed of updates, which results in high data rate and hence is suitable for LANs where bursts of up to 2 Mbytes/second are acceptable. To modify the user console: 1. Click InterfacesKVM Console. The Remote Console Settings for User page displays. SecureLinx Spider User Guide 38 6: Interfaces Figure 6-3. User Remote Console Settings Page 2. Configure the following settings: SecureLinx Spider User Guide 39 6: Interfaces KVM Console Settings for User <User drop-down menu> Select the user from the drop-down menu. The settings on this page apply only to the selected user. When a user is created by copying from an existing user, the KVM Console Settings will be copied as well. Transmission Encoding Automatic Detection This option uses an algorithm to try to determine what sort of connection is being used, and sets up parameters to match. These settings may change from login to login depending on the state of the network at that point. Preconfigured Establishes a set of parameters optimized for each of a number of connection types. The default transmission encoding is LAN (high color), which is uncompressed with a 16 bit color depth. Other data networks may be chosen from the Network speed drop-down list, and the compression and color depth will be configured accordingly. Manual Allows the direct control of the compression factor and color depth. The simplest way to reduce bandwidth is to cut the color depth down to 8 bits; subtle color shades will be gone but the overall image is very usable. Dialing up the compression level also makes available even further reductions in color depth, all the way down to black and white (1 bit.) As compression level increases and/or color depth decreases, image quality and responsiveness to changes deteriorates but required bandwidth is reduced. KVM Console Type Default Java VM Select this option to use Java on the client system launching the applet. If no Java environment is installed, the console window will not launch. The default is enabled. Sun Microsystems Java Browser Plugin Force the system to use the platform-independent Sun version instead when launching the Remote Console applet. KVM Console Deployment Note: Users have two ways to deploy the Remote Console program. Both provide the same functionality and differ only in deployment method. The default is Java Web Start. Applet deployment is available in case the user cannot connect via Java Web Start. This usually should not happen unless the user has a special proxy server or firewall that blocks Java Web Start. Java Web Start Select this option to use Java Web Start deployment method. Applet Select this option to use the Applet deployment method.

This may be changed from within the Remote Console window to allow shared access, if the user has appropriate permission. Mouse Hotkey Hotkey (Help) When the Remote Console window is open, a key code that is not captured by the client system is needed for certain mouse functions. The default is Alt+F12. Change the key code if necessary. Full-screen Hotkey Pressing Ctrl+F10 will display the KVM console in Full-screen mode while maintaining the same aspect ratio. Press Ctrl+F10 again to return to regular screen mode. The default is Ctrl+F10. Change the key code if necessary. KVM Console Virtual Keys Key Definition (Help) Button keys allow simulating keystrokes at the remote system that cannot be generated from the client keyboard. A flexible syntax allows for combinations of keys being clicked in combination or in sequence, with optional pauses and an optional confirmationbefore-sending dialog box. One key is predefined, for Ctrl+Alt+Delete (with confirmation.) The syntax to define a new Button Key is as follows: <keycode>[+|-|>[*]<keycode>]* Keycode is the key to send. Multiple key codes are concatenated with a + or a - sign. The + sign builds key combinations, all keys will be clicked until a - sign or the end of the combination is encountered. All clicked keys will be released in reversed sequence. The - sign builds single, separate key clicks and key releases. Note: For a list of keys and further explanation, click the Help link at the top of the Key Definition column. Name Enter the name to appear on the button in the Remote Console window. Up to nine Button Keys may be defined for each user. 3. Do one of the following: Click Save to save settings. Click Reset to Defaults to restore system defaults.

The Keyboard/Mouse Settings page displays. Figure 6-4. Keyboard/Mouse Settings Page A 2. Modify the following fields: Keyboard/Mouse Settings Host Interface In general, the USB interface is preferred because it provides superior mouse tracking. The Host Interface drop-down provides three selections. In the default mode, Auto, the Spider will attempt to determine whether the attached computer supports a USB keyboard/mouse. If it does, that interface will be activated, but if it does not, the Spider will fall back to PS/2. If you have a USB model Spider and the attached computer does not support USB, you will have a view-only SecureLinx Spider User Guide 42 6: Interfaces system. On the PS/2 model Spider, select PS/2 to force the PS/2 interface or USB to require USB. This selection has no effect on the USB model Spider. Force USB Full Speed Mode Some older systems do not support USB high-speed mode and may not recognize the keyboard/mouse. Enable this option for Spider to negotiate in USB full speed mode. Keyboard Model <PS/2 keyboard model drop-down menu> When operating in PS/2 interface mode, key codes from several layouts may be emulated. Generic 104-key PC for the traditional layout. Generic 109-key PC for keyboard with added Windows keys. (Use 109 for Japanese keyboard.) Apple Macintosh for Mac layout. SUN Type 6 for Sun Solaris layout. Key Release Timeout Key release timeout Network delays may sometimes result in duplicated keystrokes. Enable Key Release Timeout to fix this problem. Timeout after Enter time, in msec. Country Code Country Code Select the check box to enable the Spider to recognize the country code. Enable if the host machine requires the keyboard to send a country code to use a certain language. Most operating systems do not require this except Sun Solaris. Country From the drop-down list, select the code of the desired country. USB Mouse Type <USB mouse type drop-down menu> Different operating systems running on the target system require different mouse emulation protocols. One selection is available for newer versions of Windows and Mac OS/X, and another for Other Operating Systems (e.g., Linux). Mouse Speed Mouse speed Select the method of assigning mouse speed. Auto mouse speed determines the speed and acceleration settings of the target system. It is the recommended setting for most applications. Fixed scaling translates a one-pixel motion on the client system to a selectable number of pixels moved on the target system. As the 1 to n mapping is linear, this will only work when there is no compression acceleration or other special effects turned on at the target system. 3.

At Country Code click enabled and use the Country dropdown list to select your language choice. 7. Click Save. Figure 6-5. Keyboard/Mouse Settings Page B Video The Spider works by capturing and digitizing the analog video coming from the attached computer. This analog video may have more or less low-level electrical noise present, depending on the nature of the video card or embedded video controller. When viewed on a monitor, this noise (if random) is invisible as the display is being redrawn 60 to 100 SecureLinx Spider User Guide 44 6: Interfaces times a second. Inside the Spider, however, the algorithm sees that noise as something changing on the screen, so that requires sending off an update to the client system. This can result in a constant stream of data even when the image on the target computer’s screen is not moving. In order to avoid this, at Interface Video Miscellaneous Video Settings the Spider has a selection for noise filter. The larger filter openings will filter out more of the noise, at the cost of potentially missing small incremental changes and seeing some compression artifacts (blocky-ness). Filter settings of Normal or Large will work for most applications. Be sure to try the Remote Console Auto Adjust Video button a few times before deciding that a constant stream of data represents electrical noise requiring a larger filter setting. To modify video settings: 1. Click InterfacesVideo. The Miscellaneous Video Settings page displays. Figure 6-6. Miscellaneous Video Settings Page 2. Select the Noise Filter level from the drop-down menu. 3. Do one of the following: Click Save to save settings. Click Reset to Defaults to restore system defaults. Click Reset to restore original settings. Virtual Media The Spider provides a powerful capability called Virtual Media (or Virtual Disk). Using the USB port, the Spider can present either a local floppy disk image or a redirected remote CD-ROM image to the target computer. This can allow system recovery in conditions as SecureLinx Spider User Guide 45 6: Interfaces bad as having local disks down and no primary network connection. With Floppy Disk Image, the user can upload an image to the Spider’s memory, which then emulates a locally attached floppy drive. With CD-ROM Image, a Windows or other SAMBA share can emulate a locally attached CD-ROM, for instance to update software. Drive Redirection allows you to share (redirect) your local drive (floppy drives, hard disks, CD ROMs and other removable devices like USB sticks) with the remote system over a TCP network connection. Thus, with Drive Redirection, you can use a virtual disk drive on the remote computer instead of an image file. It is also possible to enable a remote machine to write data to your local disc. Notes: Drive Redirection supports only Windows as the client computer since it redirects based on a drive letter. For a Virtual Media demonstration see Appendix B: Virtual Media Example To open the Virtual Media page: 1. Click InterfacesVirtual Media. Figure 6-7. Virtual Media Page The functions of the Virtual Media page are discussed below. To prepare for drive redirection: 1. Enter the following: SecureLinx Spider User Guide 46 6: Interfaces Virtual Media Active Image Virtual Media Active Image Once you set Image on Windows Share or Floppy Image File (on this web page), information about the currently assigned (active) image displays. Drive Redirection Disable Drive Redirection Drive Redirection is enabled by default. Select this checkbox to disable the ability to share the local drive with the remote system. Force read-only connections Select to prevent the remote drive from writing to your local drive. Selected by default. Warning: Clearing the Force read-only connections check box may result in file system errors and data corruption because of drive caching when data is written back to the Redirected local drive. Virtual Media Options The operating system on the target computer must have a USB mass storage driver installed in order to use Virtual Media. As the BIOS on some systems does not always support mass storage emulation on the USB interface, the system default is to disable USB mass storage unless an image is loaded. This option may be unselected to use Disable USB Mass Storage Select the checkbox to disable USB mass storage if no image is loaded. Selected by default. Clear the check box if an image is loaded. Force read-only connections Select to prevent the remote drive from writing to your local drive. Selected by default. Warning: Clearing the Force read-only connections check box may result in file system errors and data corruption because of drive caching when data is written back to the Redirected local drive. 2. Do one of the following: Click Save to save settings. Click Reset to Defaults to restore system defaults. Click Reset to restore original settings. Image on Windows Share In this section of the page, you can enable the Spider to access a CD-ROM image up to 4.7 GB on a Windows shared folder via SAMBA. The Spider then makes that image accessible to the target computer by emulating a USB disk drive. Note: Windows 2003 and Windows Vista do not support this feature. Appropriate administrative permissions to access the host and file are needed, as well as the ability to see that computer over the network from the Spider. The connection remains mounted until the current user logs out or the Spider is rebooted. Other client systems logging into the Spider will see the active image in all Virtual Media pages. SecureLinx Spider User Guide 47 6: Interfaces To share a CD-ROM image: 1. Enter the following: Share Host/IP IP address of the host of the Windows shared folder. Share Name Name of the host of the Windows shared folder. Image File with Path Name and path to the CD-ROM image. User Name (optional) User name for accessing the host and file. Password (optional) Password for accessing the host and file. (The file must be structured as a CD-ROM image.) The filename appears as the Active Image and the image is available to the target computer as a letter drive (e.g., F :). 2. Do one of the following: To discard your changes, click Reset.

To log in to the Spider, a user must be authenticated by means of a password. This authentication may take place locally, where the user name and associated password are stored in the Spider’s memory. The Spider may query a centralized database using RADIUS or LDAP to determine if a given user may log in. In both of these cases, the user name must be defined on the Spider where it has its permissions assigned. Local User Management A newly assigned user has permissions inherited from an assigned group. All Local Users not associated with a group will inherit default settings.

Remote Authentication If the Spider’s Authentication Settings have been set to Local Authentication (the default), the Spider uses its own database to perform authentication. If one of the remote authentication protocols is selected, the Spider communicates with a remote server to authenticate user passwords. To configure authentication settings: 1. Click User Accounts Authentication. The Authentication Settings page displays. SecureLinx Spider User Guide 57 7: User Accounts Figure 7-4. Authentication Page 2. Modify the following fields: Local Authentication When Local Authentication is selected, the Spider will authenticate against its internal database of users and passwords, as described in Local User Management. LDAP When you select LDAP Authentication, the Spider will communicate with a Microsoft Active Directory or generic LDAP server for user authentication. The user profile must be set up in the local database as described in Local User Management, but no password is stored locally. When a user attempts to log in, the Spider contacts the specified LDAP server, which either approves or denies access. LDAP Server IP Enter the name or IP address of the LDAP server, reachable over the network by the Spider, containing the user database. Be sure to configure a DNS server if a name rather than address is used. LDAP Server Base DN Specify the Distinguished Name (DN) where the directory tree starts in the user LDAP server. LDAP Server Type Select the type of the external LDAP server. Available selections are Generic LDAP and Microsoft Active Directory. If a Generic LDAP Server is selected, edit the LDAP scheme. User Search Sub-filter Select to restrict the search for users by adding an additional search filter to each query for a user. SecureLinx Spider User Guide 58 7: User Accounts Bind Name The name for a non-anonymous bind to an LDAP server. This item has the same format as LDAP Base. One example is cn=administrator,cn=Users,dc=domain,dc=com. Bind Password and Confirm Password Password for a non-anonymous bind. This entry is optional. Acceptable characters are a-z, A-Z, and 0-9. The maximum length is 127 characters. RADIUS When RADIUS is selected, the Spider communicates with a RADIUS server for user authentication. To access a Spider set up for RADIUS, log in with a name and password. The Spider contacts the RADIUS server for authentication and, if approved, the Spider uses the locally stored user profile. If there is no such profile, access via RADIUS will be refused. Server Enter the name or IP address of the RADIUS server, reachable over the network by the Spider, containing the user database. Configure a DNS server if a name rather than an address is used. Shared Secret A shared secret is a text string that serves as a password between the RADIUS client and RADIUS server. In this case the Spider acts as a RADIUS client. A shared secret is used to verify that RADIUS messages are sent by a RADIUS-enabled device that is configured with the same shared secret and to verify that the RADIUS message has not been modified in transit (message integrity). Enter a maximum of 128 alphanumeric characters and symbols such as an exclamation point (“!”) or an asterisk (“*”). Authentication Port The port the RADIUS server listens for authentication requests. The default value is 1812. Accounting Port The port the RADIUS server listens for accounting requests. The default value is 1813. Timeout Sets the request time-to-live in seconds. The time-to-live is the time to wait for the completion of the authentication request. If the request job is not completed within this interval of time it is cancelled. The default value is 1 second. Retries Sets the number of retries if a request could not be completed. The default value is 3 times. 3. Do one of the following: Click Save to save settings. Click Reset to Defaults to restore system defaults. Click Reset to restore original settings. SecureLinx Spider User Guide 59 8: Services Date/Time The Spider contains an internal real time clock that maintains a basic date and time after being set. The clock, however, will reset if the unit loses power. If an accurate date and time are critical, the Spider supports synchronization with Network Time Protocol servers. Internally, the date and time are only used to timestamp events in the log and for the inactivity timeout. To configure the date and time settings: 1. Click ServicesDate/Time. The Date/Time Settings page displays. Figure 8-1. Date/Time Settings Page 2. Modify the following fields: UTC Offset Time servers deliver time as Coordinated Universal Time (UTC, or Greenwich Mean Time). Select the appropriate offset in hours ± from the drop-down menu. User Specified Time Manually input the current date and time. The Spider keeps time as long as power is applied. It has an internal calendar, but does not know about daylight savings time and requires resetting twice a year. The internal clock accuracy is ±30 ppm. Synchronize with NTP Enter a primary and secondary time server in the respective SecureLinx Spider User Guide 60 8: Services Server fields. Ensure NAT and firewalls are set up to allow the protocol to pass. Also, provide the Spider with DNS server names. 3. Do one of the following: Click Save to save settings. Click Reset to Defaults to restore system defaults. Click Reset to restore original settings. Security General settings for security parameters such as encryption and access control are at Services Security. Other areas with security implications include User Management/Permissions, Authentication, Network Settings, and the Event Log; see the appropriate sections for information on those areas. To modify security settings: 1. Click Services Security. The Security page displays. Figure 8-2. Security Settings Page 2. Modify the following fields: SecureLinx Spider User Guide 61 8: Services HTTP Encryption Force HTTPS for Web Access Typically, the Spider listens on both HTTP and HTTPS ports for incoming connections. If this box is checked, access can only be made using SSL, and connection requests on the HTTP port will be ignored. See the section on Certificate for further information on how the Spider identifies itself using a cryptographic certificate. Login Limitations Enable Single Login Limitation If this box is checked, each username may only have one logged in connection at a time. If unchecked, multiple instances of username logins are allowed. KVM Encryption KVM Encryption In addition to the SSL encryption of the Spider’s web pages, the keyboard, mouse, and video data may be encrypted. Select Off to use no encryption. Select Try for the Spider to attempt to make an encrypted connection but will back off to unencrypted if one cannot be established. Select Force for an encrypted connection to be made, or an error will be reported. Group Based System Access Control Enable Group Based System Access Control When this box is checked, the rules for IP based access are enforced. They are ignored when the box is not checked. Default Action If after evaluation of all rules a request for connection from a given IP address has not had either an Accept or Drop decision made, this selection can allow it to be either Accepted or Dropped. In other words, this drop-down defines the default action for IP addresses with no rules defined. Rule creation and editing Spiders come from the factory with one rule defined as an example of the rule structure: Rule 1 allows all groups access from source IP 0.0.0.0 to 255.255.255.255. Additional rules may be entered in the edit boxes. Rule Number: Defines where in the evaluation sequence this rule is to be applied. Starting and Ending IP Addresses: Define the range over which the rule applies. Group: Defines which user group is affected by this rule. Built-in groups include Admin, All, and Unknown (no group assigned). As additional groups are defined in User Management Users Group Management, they will appear in the drop-down. A rule can apply to only one group at a time. Action: Chooses whether this is to be a Drop or Accept rule. After a rule has been defined, it needs to go in the correct place in the list. Append: Puts the rule at the end of the list. The rule number changes to reflect the last position on the list. Insert: Puts the rule in the place on the list indicated by the rule number, renumbering and moving down the other rules to make SecureLinx Spider User Guide 62 8: Services room. Replace: Deletes the previous rule of that number and replaces it with the new rule. Delete: Deletes the rule of that number and moves the others up. Note that for a Delete, the fields other than the rule number do not need to be filled in. Authentication Limitation Enable Screenshot Access without Authentication Select this option when you need to access the snapshot image without logging in to the Spider. If enabled, the screenshot can be read directly with http(s)://<spiderIPaddress>/screenshot.jpg. One use of this unauthenticated screenshot is to read it from a Google gadget Enable Direct KVM Console Access without Authentication Select this option to launch the Remote Console without authentication by entering the Spider's IP address (http(s):/(Spider IP address) in the browser's Address field or type javaws http(s):/(Spider IP address in the command line. To launch Spider web access type http(s):/(Spider IP address)/home in the browser’s Address field. 3. Do one of the following: Click Save to save settings. Click Reset to Defaults to restore system defaults. Click Reset to restore original settings. Certificate The Spider uses the Secure Socket Layer (SSL) protocol for any encrypted network traffic between itself and a connected client. During the connection establishment the Spider has to expose its identity to a client using a cryptographic certificate. Upon leaving the factory this certificate and the underlying secret key is the same for all Spiders and will not match the network configuration where it is installed. The certificate’s underlying secret key is also used for securing the SSL handshake. Leaving the default certificate unmodified is all right in most circumstances and is necessary only if the network facility is vulnerable to man-in-the-middle attack. It is possible to generate and install a new base64 x.509 certificate that is unique for a particular Spider. The Spider is able to generate a new cryptographic key and the associated Certificate Signing Request (CSR) that needs to be certified by a certification authority (CA). To create and install an SSL certificate: 1. Click Services Certificate. The Certificate Signing Request page displays. SecureLinx Spider User Guide 63 8: Services Figure 8-3. Certificate Signing Request Page 2. Modify the following fields: Common name The network name of the Spider once it is installed in the user’s network (usually the fully qualified domain name). It is identical to the name that is used to access the Spider with a web browser without the prefix http://. In case the name given here and the actual network name differ, the browser will pop up a security warning when the Spider is accessed using HTTPS. Organizational unit This field specifies to the department within an organization to which the Spider belongs. Organization The name of the organization to which the Spider belongs. Locality/City The city where the organization is located. State/Province The state or province where the organization is located. Country (ISO code) The country where the organization is located. This is the two-letter ISO code (e.g., US for the United States). Email The email address of a contact person responsible for the Spider and its security. Challenge password/Confirm Challenge password Certain certification authorities require a challenge password to authorize later changes on the certificate (e.g., revocation of the certificate). The minimal length of this password is four characters. Key length (bits) Select the key length from the drop-down menu. 3. Click Create to initiate the Certificate Signing Request generation. Download the CSR by clicking Download. The Download button displays when a certificate is created. Send the saved CSR to a CA for certification. 4. Click Upload to upload the certificate from the client computer to the Spider. The Spider now has its own certificate used for identifying itself to its clients. SecureLinx Spider User Guide 64 8: Services Event Log The Event Log maintains a list of significant events locally. Alternatively it can use an NFS log file, SMTP email, or SNMP to distribute event information on the network. The Spider monitors five classes of events with the logging of each enabled or disabled. To configure event log settings: 1. Click Services Event Log. The Event Log page displays. Figure 8-4. Event Log Page 2. Modify the following fields: Event Log Targets List Logging Enabled Check this box to use the internal log list of the Spider. The maximum number of entries is 1,000. Every entry that exceeds this limit overrides the oldest one. The number of log entries shown on each page may be changed in the text box. The internal log list is cleared when power is removed from the Spider, or when you click the Clear button. NFS Logging Enabled The Spider can write log information to a file on an NFS server. Provide the name of the server, share, and file in the boxes. The NFS share will be mounted immediately, and an error message will result if it cannot be found. SMTP Logging enabled With this option, the Spider is able to send emails to an address given by the email address. These emails contain the same SecureLinx Spider User Guide 65 8: Services description strings as the internal log file and the mail subject contains the event class. To use this log destination, specify an SMTP Server, the Receiver Email Address, and Sender Email Address. Enter the mail server and SMTP port as <serverip>:<port>. SNMP Logging Enabled If selected, the Spider sends an SNMP trap to a specified destination IP address every time a log event occurs. Configure the Destination IP and Community. View the SNMP MIB implemented in the Spider by clicking on the SLS SNMP MIB link.

Examples are devicegroup, account, and network. <parameter(s)> is one or more name-value pairs in one of the following formats: <parameter name> <aabb> Specify one of the values (aa or bb) separated by a vertical line ( | ). The values are all lowercase and must be entered exactly as shown. Bold indicates a default value. <parameter name> <Value> Specify an appropriate value, for example, a device group name. Square brackets [ ] This User Guide shows parameter values in mixed case to indicate they are case sensitive. For example, if you saved a device group name in mixed case, you must enter it in mixed case; if you saved it in lowercase, you must enter it in lowercase. Indicate optional parameters. Figure 10-1. Action and Category Options Action set show connect admin diag Category datetime|group|history|network|security|serial|sshkey|user|vip datetime|group|history|network|security|serial|sshkey|sysconfig|user| vip serial config|reboot|version ping SecureLinx Spider User Guide 77 10: Command Line Interface (CLI) Terminates CLI session. logout Command Help For general command help, type: help For more information about a specific command, type help followed by the command, for example: help set network OR type ? after the command: set network ? Tips Type enough characters to identify the action, category, or parameter name uniquely. For parameter values, type the entire value. For example, set network port 1 state static ipaddr 122.3.10.1 mask 255.255.0.0 can be shortened to: se net po 1 st static ip 122.3.10.1 ma 255.255.0.0 Use the Tab key to automatically complete action, category, or parameter names. Type a partial name and press Tab to complete the name if only one is possible, or to display the possible names if more than one is possible. Should you make a mistake while typing, backspace by pressing the Backspace key or the Delete key, depending on how you accessed the interface. Both keys work if you use VT100 emulation in your terminal access program when connecting to the console port. Use the left and right arrow keys to move within a command. Use the up and down arrows to scroll through previously entered commands. If desired, select one and edit it. You can scroll through up to 100 previous commands entered in the session. When the number of lines displayed by a command exceeds the size of the window (the default is 20), the "Type more to see the next page" message displays. To display the next page, type more and press Enter. You can override the number of lines (or disable the feature altogether) with the set cli command. To clear an IP address, type 0.0.0.0.

SecureLinx Spider User Guide 84 11: ManageLinx Integration and Configuration The Spider provides secure remote Internet access to virtually any computer. You can easily configure Spider to ManageLinx without using a DSC. Adding a Device or Device Server Device and device server elements represent the actual devices you will communicate with over the Virtual Device Network. A device server is usually a Lantronix hardware item (e.g. XPort, MatchPort). A device is usually a non-Lantronix hardware item (e.g. webcam). You must link each of these devices to a DSC via a physical network. 1. Open your internet browser (I.E. 6.0 or later) or (Firefox 2.0 or later). 2. Enter the IP address of the DSM. 3. Log in using sysadmin as the user name and PASS as the password. 4. On the DSM Web Manager, click CONFIGURATION. Figure 11-1. Login Screen SecureLinx Spider User Guide 85 11: ManageLinx Integration and Configuration By default two DSCs are already shown on the map. You may skip the next two steps unless you want to add more DSCs at this time. 5. On the command menu, click ADD DSC. 6. Click anywhere on the map.

This will launch KVM console if you enable direct KVM console or launch web access. You can also use SpiderView. Figure 11-8. KVM Console SecureLinx Spider User Guide 89 11: ManageLinx Integration and Configuration Figure 11-9. Spider View SecureLinx Spider User Guide 90 A: Troubleshooting 1. No connection can be established to the Spider Check cabling. Are both USB cables or all of the USB and PS/2 cables plugged in? Are both Pwr LEDs lit? Is the Ethernet cable plugged in, and the Link light lit? Is there Activity? Have a look on your network. Verify your network configuration (IP address, router). Send a ping request to the Spider to find out whether the Spider is reachable via the network. Establish a direct connection between the Spider and the client. If you use a firewall then check the appropriate port for accepting connections. The TCP ports 80 (for HTTP) and 443 (for both HTTPS and RFB) have to be open (the server providing the firewall has to accept incoming TCP connections on these ports). You may restrict these connections to the IP addresses used by the Spider and your client. 2. Login on the Spider fails. Verify both your user login and your password. By default, the user sysadmin has the password PASS. Ensure the web browser is configured to accept cookies. 3. The Remote Console window of the Spider does not open. A firewall may prevent access to the Remote Console (TCP port 443). If there is a proxy server between the Spider and your host, then you may not be able to transfer the video data using RFB. Check the settings of the Spider and choose a different server port used for RFB transfer. A Java Runtime Environment may not be installed, or may be disabled. 4. The video quality is bad or the picture is grainy. Enter the Remote Console and click the Auto Adjust button to adjust the Spider’s video input parameters to the correct values. 5. Special key combinations (e.g., ALT+F2, ALT+F3) are intercepted by the client system and not transmitted to the remote computer. You have to define a Button Key. This can be done in the Remote Console settings. Alternatively, use the soft keyboard feature. 6. The Spider web pages are not displayed correctly. Check your browser’s cache settings. Ensure the cache settings are not set to “do not check for newer pages." Otherwise the web pages may be loaded from your browser cache and not from the Spider. 7. Every time I open a dialog box with some buttons, the mouse pointers are not synchronous anymore. Disable the setting Automatically move mouse pointer to the default button of dialog boxes in the mouse settings of your operating system. SecureLinx Spider User Guide 91 A: Troubleshooting 8. The Remote Console does not open with Opera in Linux. Some versions of Opera do not grant enough permission if the signature of the applet cannot be verified. To solve the problem, add the lines grantcodeBase "nn.pp.rc.RemoteConsoleApplet" {permission java.lang.RuntimePermission "accessClassInPackage.sun.*"; to the java policy file of opera (e.g., /usr/share/opera/java/opera.policy). 9. I forgot my password. How can I reset the Spider to factory defaults? Use the serial interface with a terminal emulator program set to 115200, 8, None, 1, No flow control. Within 2 seconds of booting the Spider, enter the Esc key a few times to get a prompt. Enter Defaults. 10. Cannot upload the signed SSL certificate in MacOS X. If an “internal error” occurs while uploading the signed certificate either changes the extension of the file to .txt or adds a file helper using the Internet Explorer preferences for this type of file. Make sure that the encoding is set to “plain text” and the checkbox “use for outgoing” is set. As an alternative, you may also use a Mozilla based browser (Mozilla, FireFox). 11. If you cannot get into the BIOS of your system or you cannot boot your system using Virtual Media, try some of the following: If you have a PS/2 model Spider: a) Under Interfaces:Keyboard/Mouse – Check the Force USB Full Speed Mode box. b) Under Interfaces:Keyboard/Mouse – Set the Host Interface to PS/2 c) If your system only has USB and no PS/2, do the above and use a PS/2 to USB adapter If you have a USB model Spider : d) Under Interfaces:Keyboard/Mouse – Check the Force USB Full Speed Mode box. If the key used to enter BIOS setup or the boot menu on your PC is intercepted by your client OS, add a Virtual Key under Interfaces:KVM Console Settings. SecureLinx Spider User Guide 92 B: Virtual Media Example Goal In this example, the goal is to put a rescue CD (a CD used to boot a PC when the harddisk corruption prevents OS boot) on PC#3 so that the rescue CD can be used by any Spiders on the network. Figure B-1. Virtual Media In this example, PC#2 cannot boot from its hard disk, so the user wants to use the rescue CD to boot the PC. We assume PC#2 can boot from external USB device. SecureLinx Spider User Guide 93 B: Virtual Media Example Step 1 – Prepare the VM Server 1. Use any CD-copy application to create an ISO image of the rescue CD, and call this ISO image file boot.iso. 2. On PC#3 (Windows XP in this example), put the ISO file in a Windows folder – file boot.iso in folder aaa as shown in the diagram below. Figure B-2. Windows Browser 3. Right-click the folder aaa and select the “sharing” menu. The default name is the folder name but changed to share_some_folder as shown in the diagram below. SecureLinx Spider User Guide 94 B: Virtual Media Example Figure B-3. Firewall Properties Window Now, the file boot.iso can be used from a Spider. The file can be left there permanently, and when a PC/server crashes and cannot boot, the combination of this file and the Spider will be used to boot the PC/server. SecureLinx Spider User Guide 95 B: Virtual Media Example Step 2 – Enable Virtual Media In this example, PC#2 does not respond, and rebooting does not cure the problem. PC#2 has Spider#2 attached. 1. On any PC (call this the client PC), bring up a browser, browse to Spider#2, and log in. 2. Go to the Virtual Media page and complete the fields in the Image on Windows Share section of the page as shown in the diagram below. Figure B-4. Virtual Media Page SecureLinx Spider User Guide 96 B: Virtual Media Example 3. Click Set, and see that the Virtual Media Active Image section now contains data as shown in the diagram below. Figure B-5. Virtual Media Active Image Step 3 – Use the Virtual Media PC#2 shown in the diagram below is a Linux PC. SecureLinx Spider User Guide 97 B: Virtual Media Example Figure B-6. Linux PC Window Once step 2 is done, PC#2 will detect a new USB CD drive connected to its USB as shown in the diagram below. The CD is shown below as Fedora Core because that is the volume name of the rescue CD (boot.iso is the ISO image of this CD). Figure B-7. Linux PC Window and USB CD You should be able to boot from the external USB device (boot.iso) on PC#2. Make sure that you set BIOS to boot from the USB device. Note: Some systems may not support USB boot.
